PROXY STATEMENT

FOR

ANNUAL MEETING OF STOCKHOLDERS

MAY 19, 2006

INTRODUCTION

General

This proxy statement is furnished to our stockholders in connection with the solicitation of proxies for use at our annual meeting of stockholders to be held on May 19, 2006 at 2:30 p.m., Pacific time, for the purposes as set forth in the “Notice of Annual Meeting of Stockholders”.

A copy of our Annual Report on Form 10-K for the year ended December 31, 2005 and this proxy statement and accompanying proxy card will be first mailed to stockholders on or about April 13, 2006.

This solicitation is made on behalf of our Board of Directors and we will pay the costs of solicitation. Our directors, officers and employees may also solicit proxies by telephone, fax or personal interview. We will reimburse banks, brokerage firms and other custodians, nominees and fiduciaries for reasonable expenses incurred by them in sending proxy material to our stockholders. We have retained Computershare Trust Co. to assist in the solicitation of proxies with respect to shares of our common stock held of record by brokers, nominees and institutions for a customary fee.

Our principal executive offices are located at 950 Kifer Road, Sunnyvale, California 94086, telephone (408) 523-2100.

Shares Entitled to Vote and Required Vote

Our outstanding common stock constitutes the only class of securities entitled to vote at the annual meeting. Stockholders of record of the common stock at the close of business on April 5, 2006 are entitled to notice of, and to vote at, the annual meeting. A list of our stockholders will be available for review at our principal executive offices during regular business hours for a period of 10 days prior to the annual meeting. As of April 5, 2006, 36,540,957 shares of our common stock were issued and outstanding. The presence at the meeting, in person or by proxy, of a majority of the shares of the common stock issued and outstanding on April 5, 2006 will constitute a quorum. Each share of common stock is entitled to one vote.

Voting Procedures

A proxy card is enclosed for your use. We ask that you complete, sign, date and return the proxy card in the accompanying envelope, which is postage prepaid if you mail it in the United States.

You have choices on the matter to be voted upon at the annual meeting. By checking the appropriate box on your proxy card you may:

• vote for the director nominees listed in Proposal No. 1; or

• withhold authority to vote for some or all of the director nominees.

Unless there are different instructions on the proxy, all shares represented by valid proxies (and not revoked before they are voted) will be voted at the meeting FOR the election of the director nominees listed in Proposal No. 1. With respect to any other business which may properly come before the annual meeting and be submitted to a vote of stockholders, proxies will be voted in accordance with the best judgment of the designated proxy holders.

Shares represented by proxies that reflect abstentions or “broker non-votes” (i.e., shares held by a broker or nominee which are represented at the meeting, but with respect to which the broker or nominee is not empowered to vote on a particular proposal) will be counted as shares that are present and entitled to vote for purposes of determining the presence of a quorum. Broker non-votes are not deemed to be entitled to vote for purposes of determining whether stockholder approval of a matter has been obtained. As a result, broker non-votes are not included in the tabulation of voting results on any proposal. The director nominees listed in Proposal No. 1 will be elected by a plurality of the votes of the shares present or represented by proxy at the meeting and entitled to vote on the election of directors.

Stockholders of record may vote by either completing and returning the enclosed proxy card prior to the meeting, voting in person at the meeting, or submitting a signed proxy card at the meeting.

Your vote is important. Accordingly, please complete, sign, date and return the accompanying proxy card whether or not you plan to attend the annual meeting in person.

You may revoke your proxy at any time before it is actually voted at the meeting by:

• delivering written notice of revocation to our Secretary at 950 Kifer Road, Sunnyvale, California 94086;

• submitting a later dated proxy; or

• attending the meeting and voting in person.

Your attendance at the meeting will not, by itself, constitute revocation of your proxy. You may also be represented by another person present at the meeting by executing a form of proxy designating that person to act on your behalf. Shares may only be voted by or on behalf of the record holder of shares as indicated in our stock transfer records. If you are a beneficial stockholder but your shares are held of record by another person, such as a stock brokerage firm or bank, that person must vote the shares as the record holders in accordance with the beneficial holder’s instructions.

All votes cast at the meeting will be tabulated by the persons appointed by us to act as inspectors of election for the meeting.

In addition, non-employee directors receive an annual fee of $10,000 payable in equal quarterly installments. Committee members receive $500 for each committee meeting they attend on a day other than a day on which a board meeting is held.

Pursuant to our 2000 Non-Employee Directors’ Stock Option Plan, non-employee directors receive (1) an initial option to purchase 15,000 shares of common stock, (2) 7,500 shares of common stock at each annual meeting and (3) committee chairs receive an additional option to purchase 2,500 shares of common stock at each annual meeting.

Committees of the Board of Directors

During 2005, our Board of Directors held six meetings and each director, other than Mr. Halvorson, attended at least 75% of those meetings. Mr. Halvorson attended four of the six meetings. Our Board of Directors has three standing committees: the Audit Committee, the Compensation Committee and the Governance and Nominating Committee.

5

The Audit Committee assists the full Board of Directors in its general oversight of our financial reporting, internal controls, and audit functions, and is directly responsible for the appointment, compensation and oversight of the work of our independent registered public accounting firm. The members of the Audit Committee are William J. Mercer, Richard J. Kramer and Eric H. Halvorson, each an independent director as defined by the listing standards of the Nasdaq National Market relating to audit committee members. In 2005, the Audit Committee met nine times and each current member of the Audit Committee attended at least 75% of those meetings. The Board of Directors has adopted a written charter for the Audit Committee, a copy of which was attached as Annex A to the proxy statement for our 2004 Annual Meeting of Stockholders. The Board of Directors has determined that Mr. Kramer is an “Audit Committee Financial Expert”, as defined in Item 401(h) of Regulation S-K.

The Compensation Committee establishes our executive compensation policy, determines the salary and bonuses of our executive officers and recommends to the Board of Directors stock option grants for our executive officers. The members of the Compensation Committee are Alan J. Levy, Ph.D. and D. Keith Grossman, each an independent director as defined by the listing standards of the Nasdaq National Market. In 2005, the Compensation Committee met five times and both current members of the Compensation Committee attended all of those meetings.

The Governance and Nominating Committee is responsible for matters relating to the corporate governance of our company and the nomination of members of the board and committees thereof. The members of the Governance and Nominating Committee are Alan J. Levy, Ph.D., Eric H. Halvorson and Floyd Loop, M.D. each an independent director as defined by the listing standards of the Nasdaq National Market. In 2005, the Governance and Nominating Committee met three times and each current member of the Governance and Nominating Committee attended all of those meetings. A copy of the charter is attached as Annex B to the proxy statement for our 2004 Annual Meeting of Stockholders.

Nomination Process

The Governance and Nominating Committee identifies director nominees by first evaluating the current members of the Board of Directors willing to continue in service. Current members with skills and experience that are relevant to our business and are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of the Board of Directors with that of obtaining a new perspective. If any member of the Board of Directors does not wish to continue in service or the Committee or Board of Directors decides not to re-nominate a member for re-election, the Committee identifies the desired skills and experience of a new nominee consistent with the Committee’s criteria for Board of Directors service. Current members of the Board of Directors and management are polled for their recommendations. Research may also be performed or third parties retained to identify qualified individuals. To date, we have not engaged third parties to identify or evaluate potential nominees; however, we may in the future choose to do so.

The Governance and Nominating Committee will consider nominees recommended by stockholders, and any such recommendations should be forwarded to the Governance and Nominating Committee in writing at our executive offices as identified in this proxy statement. Such recommendations should include the following information:

• such information as may be reasonably necessary to determine whether the recommended director candidate is independent from the security holder that has recommended the candidate;

• such information as may be reasonably necessary to determine whether the director candidate is qualified to serve on the Audit Committee; and

• such information as may be reasonably necessary to determine whether the director candidate meets the independence standards of the Nasdaq National Market.

6

We will also request such other information as may reasonably be required to determine whether each person recommended by a security holder meets the criteria listed below and to enable us to make appropriate disclosures to the security holders entitled to vote in the election of directors. Any recommendations received from stockholders will be evaluated in the same manner as potential nominees suggested by board members, management or other parties.

The Governance and Nominating Committee evaluates director candidates based upon a number of criteria, including:

• commitment to promoting the long term interests of the Company’s security holders and independence from any particular constituency;

• professional and personal reputations that are consistent with our values;

• broad general business experience and acumen, which may include experience in management, finance, marketing and accounting, across a broad range of industries with particular emphasis on healthcare and medical device industries, along with experience operating at a policy-making level in an appropriate business, financial, governmental, educational, non-profit, technological or global field;

• a high level of personal and professional integrity;

• adequate time to devote attention to the affairs of the company;

• such other attributes, including independence, relevant in constituting a board that also satisfies the requirements imposed by the Securities and Exchange Commission and the Nasdaq National Market; and

• board balance in light of our company’s current and anticipated needs and the attributes of the other directors and executives.

Security Holder Communication with Board Members

Any holder of our securities may contact the Board of Directors or a specified individual director by writing to the attention of the Board of Directors or a specified individual director and sending such communication to our investor relations department at our executive offices as identified in this proxy statement. Each communication from a securityholder should include the following information in order to permit securityholder status to be confirmed and to provide an address to forward a response if deemed appropriate:

• the name, mailing address and telephone number of the security holder sending the communication;

• the number and type of our securities owned by such security holder; and

• if the security holder is not a record owner of our securities, the name of the record owner of our securities beneficially owned by the security holder.

Our investor relations department will forward all appropriate communications to the Board of Directors or individual members of the Board of Directors as specified in the communication. Our investor relations department may (but is not required to) review all correspondence addressed to the Board of Directors, or any individual member of the Board of Directors, for any inappropriate correspondence more suitably directed to management. Communications may be deemed inappropriate for this purpose if it is reasonably apparent from the face of the correspondence that it relates principally to a customer dispute involving the purchase of goods or services from the company or any of its operating units. Our policies regarding the handling of security holder communications were approved by a majority of our independent directors.

Annual Meeting Attendance

The policy of the Board of Directors is that all directors attend the annual meeting of stockholders, absent compelling circumstances that prevent attendance. All directors attended the annual meeting of stockholders held in 2005.

7

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

During 2005, we believe that there has not been any transaction or series of similar transactions to which we were or are to be a party in which the amount involved exceeds $60,000 and in which any director, executive officer or holder of more than 5% of our common stock, or members of any such person’s immediate family, had or will have a direct or indirect material interest, other than compensation described in “Executive Compensation.” We intend that any such future transactions will be approved by the Audit Committee of the Board of Directors and will be on terms no less favorable to our company than could be obtained from unaffiliated third parties.

COMPENSATION COMMITTEE REPORT

The Compensation Committee is responsible for establishing and monitoring the general compensation policies and compensation plans of our company, as well as the specific compensation levels for executive officers. The Compensation Committee also has the authority and power to grant stock options under our 2000 Equity Incentive Plan. Executive officers who are also directors have not participated in deliberations or decisions involving their own compensation.

The following is the Compensation Committee’s report submitted to the Board of Directors addressing the compensation of our executive officers for 2005.

Compensation Policy and Philosophy

Our executive compensation policy is designed to:

• attract and retain qualified executives who will contribute to our long-term success;

• reward executives for achieving our goals; and

• link executive compensation and stockholder interests through equity-based plans.

We believe that in order to attract and retain qualified executives, our compensation policies must be competitive with comparable companies in similar industries. The compensation mix reflects a balance of cash payments, consisting of base salary and cash bonus payments, and long-term stock-based incentives in the form of stock options. The emphasis in incentive compensation is placed on stock options that more closely align the financial interests of our employees with our stockholders.

Executive Compensation Components

As discussed below, our executive compensation package is primarily comprised of three components: base salary, annual incentive bonuses, and stock options.

Base Salary. The Compensation Committee establishes base salaries for executive officers based on its review of the base salaries of executive officers in comparable companies and in similar industries. Base salaries for executives are reviewed annually and adjusted based on industry compensation surveys as well as each executive officer’s experience and performance in achieving our company’s objectives.

Annual Incentive Bonuses. Our Corporate Incentive Plan provides a cash incentive opportunity for all non-commissioned employees, including executive officers. Achievement of specific company metrics determine overall plan payment levels, then group performance levels are applied, and finally individual performance levels are considered to determine individual incentive payments. Bonuses were paid to employees and executives in 2006 for performance achieved during 2005.

8

Long Term Incentive Compensation. Our equity incentive plans provide for long-term incentive compensation for our employees including executive officers. A significant portion of the total compensation package for our executive officers is in the form of stock option awards. These awards give employees an equity interest in our company, thereby aligning the interests of executive officers and stockholders and providing incentive to maximize stockholder value. Stock option positions for all employees, including executives, were reviewed in 2005 and adjusted based on industry surveys, number of options previously granted, as well as contributions to our success.

Compensation of Chief Executive Officer

The compensation for our Chief Executive Officer, Lonnie Smith, for 2005 was comprised of base salary, annual incentive bonus, and long-term incentive compensation in the form of stock options. The Compensation Committee regularly reviews the performance and compensation of Mr. Smith following the criteria discussed above. The Compensation Committee awarded stock options and a cash bonus to Mr. Smith in February 2005. The Compensation Committee awarded an increase in base salary to Mr. Smith in July 2005.

Internal Revenue Code Section 162(m)

Section 162(m) of the Internal Revenue Code limits our tax deduction to $1 million for compensation paid to certain executive officers named in this proxy statement unless the compensation is performance-based. Since the cash compensation paid by our company to each of its executive officers is expected to be well below $1 million and the Compensation Committee believes that options granted would meet the requirements for qualifying as performance-based, the Compensation Committee believes that these limitations did not impact our company in 2005. It is the Compensation Committee’s intention to qualify, to the extent reasonable, the executive officers’ compensation for deductibility under applicable tax law.

Alan J. Levy, Ph.D.

The foregoing Compensation Committee report shall not be deemed incorporated by reference into any filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, and shall not otherwise be deemed filed under these acts, except to the extent we incorporate by reference into such filings.

Employment Agreement

In February 1997, we entered into an agreement with Lonnie M. Smith, our President and Chief Executive Officer, providing that, in the case of involuntary termination other than for cause, his salary and benefits will continue to be paid for a period of one year from the date of termination. Cause as defined in the agreement includes conviction for any felony, participation in a fraud or act of dishonesty against us, willful breach of our policies, or a material breach by Mr. Smith of his employment agreement or of his proprietary information and inventions agreement.

Option Grants in 2005

The table below sets forth each grant of stock options during 2005 to each of our named executive officers. Options were granted at an exercise price equal to the closing sale price of the common stock on the Nasdaq National Market on that date.

The potential realizable value is calculated based on the ten-year term of the option at the time of grant. Stock price appreciation of 5% and 10% is assumed pursuant to rules promulgated by the Securities and Exchange Commission and does not represent our prediction of our stock price performance. The potential realizable values at 5% and 10% appreciation are calculated by:

• Multiplying the number of shares of common stock subject to a given option by the fair market value at the date of grant;

• Assuming that the aggregate stock value derived from that calculation compounds at the annual 5% or 10% rate shown in the table until the expiration of the options; and

• Subtracting from that result the aggregate option exercise price.

11

The shares listed in the following table under “Number of Securities Underlying Options Granted” are subject to vesting. Upon completion of six months of service from the vesting start date, 12.5% of the option shares vest and the balance vests in a series of equal monthly installments over the next 42 months of service. The option has a ten-year term, subject to earlier termination if the optionee’s service with us ceases.

Percentages shown under “Percentage of Total Options Granted to Employees in Fiscal Year 2005” are based on an aggregate of 1,200,955 options granted to our employees under our stock option plans during 2005.

	Individual Grants
	Number of Securities Underlying Options Granted	Percentage of Total Options Granted to Employees in Fiscal Year 2005		Exercise Price Per Share		Expiration Date	Potential Realizable Value at Assumed Annual Rates of Stock Price Appreciation for Option Term

Year-End Option Values

The table below sets forth information regarding option exercises by our named executive officers in 2005, as well as the number and value of securities underlying unexercised options that are held by each of the individuals listed in the summary compensation table as of December 31, 2005.

Amounts shown under the column “Value Realized” are based on the market value of the underlying securities on the exercise date, less the exercise price for these shares.

Amounts shown under the column “Value of Unexercised In-The-Money Options at December 31, 2005” are based on the closing market price of $117.27 on that date, without taking into account any taxes that may be payable in connection with the transaction, multiplied by the number of shares underlying the option, less the exercise price payable for these shares.

Name	Number of Shares Acquired on Exercise	Value Realized		Number of Securities Underlying Unexercised Options at December 31, 2005		Value of Unexercised In-the-Money Options at December 31, 2005

Compensation Committee Interlocks and Insider Participation

During 2005, the Compensation Committee consisted of Alan J. Levy, Ph.D. and Keith Grossman, none of whom is a present or former officer or employee of our company. In addition, during 2005, none of our officers had an “interlock” relationship, as that term is defined by the SEC, to report.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires that our executive officers and directors, and persons who own more than 10% of a registered class of our equity securities, file reports of ownership and changes in ownership (Forms 3, 4 and 5) with the Securities and Exchange Commission. Executive officers, directors and greater-than-10% holders are required to furnish us with copies of all of these forms which they file.

Based solely on our review of these reports or written representations from certain reporting persons, we believe that during 2005, all filing requirements applicable to our officers, directors, greater-than-10% beneficial owners and other persons subject to Section 16(a) of the Exchange Act were met.

AUDIT COMMITTEE REPORT

Our Audit Committee is composed of “independent” directors, as determined in accordance with Rule 4200(a)(15) of the Nasdaq Stock Market’s regulations and Rule 10A-3 of the Securities Exchange Act of 1934. The Audit Committee operates pursuant to a written charter adopted by the Board of Directors, a copy of which was attached as Annex A to the proxy statement for our 2004 annual meeting of stockholders.

As described more fully in its charter, the purpose of the Audit Committee is to assist the Board of Directors with its oversight responsibilities regarding the integrity of our company’s financial statements, our compliance with legal and regulatory requirements, assessing the independent registered public accounting firm’s qualifications and independence and the performance of the persons performing internal audit duties for our company and the independent registered public accounting firm. Management is responsible for preparation, presentation and integrity of our financial statements as well as our financial reporting process, accounting policies, internal audit function, internal accounting controls and disclosure controls and procedures. The independent registered public accounting firm is responsible for performing an independent audit of our consolidated financial statements in accordance with generally accepted auditing standards and to issue a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes. The following is the Audit Committee’s report submitted to the Board of Directors for 2005.

The Audit Committee has:

• reviewed and discussed our audited financial statements with management and Ernst & Young LLP, the independent accountants;

• discussed with Ernst & Young LLP the matters required to be discussed by Statement on Auditing Standards No. 61, Communications with Audit Committees, as may be modified or supplemented; and

• received from Ernst & Young LLP the written disclosures and the letter regarding their independence as required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, as may be modified or supplemented, and discussed the auditors’ independence with them.

In addition, the Audit Committee has met separately with management, with persons performing internal audit duties for our company and with Ernst & Young LLP.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2005 for filing with the Securities and Exchange Commission.

OTHER INFORMATION

Other Matters at the Annual Meeting

We do not know of any matters to be presented at the annual meeting other than those mentioned in this proxy statement. If any other matters are properly brought before the annual meeting, it is intended that the proxies will be voted in accordance with the best judgment of the person or persons voting the proxies.

Principal Accountant Fees and Services

Our auditors for the year ended December 31, 2005 were Ernst & Young LLP. We expect that Ernst & Young LLP will serve as our auditors for fiscal year 2006. A representative of Ernst & Young LLP will be present at the annual meeting, will have an opportunity to make a statement if he so desires and is expected to be available to respond to appropriate questions. All of the services described in the following fee table were approved in conformity with the Audit Committee’s pre-approval process.

	2005		2004
Audit fees	$	1,120,076	$	731,000
Audit-related fees	$	25,000	$	22,500
Tax fees	$	53,500	$	38,000
All other fees	$	1,500	$	1,500
Total	$	1,200,076	$	793,000

Audit Fees. This category includes the audit of our annual financial statements, the audit of management’s assessment of our internal control over financial reporting, review of financial statements included in our Form 10-Q quarterly reports, and services that are normally provided by the independent registered public accounting firm in connection with statutory and regulatory filings or engagements, for those fiscal years. This category also includes advice on accounting matters that arose during, or as a result of, the audit or the review of interim financial statements and the preparation of an annual “management letter” on internal control matters.

Audit-Related Fees. This category consists of assurance and related services provided by Ernst & Young that are reasonably related to the performance of the audit or review of our financial statements and are not reported above under “Audit Fees.” The services for the fees disclosed under this category include benefit plan audits.

Tax Fees. This category consists of services provided by Ernst & Young for tax compliance, tax advice, and tax planning.

All Other Fees. This category consists of all other services provided by Ernst & Young that are not reported above. The services for the fees disclosed under this category include an annual subscription fee to Ernst & Young for accounting literature.

Pre-Approval Policies and Procedures

All audit services, audit-related services, tax services and other services were pre-approved by our Audit Committee, which concluded that the provision of such services by Ernst & Young LLP was compatible with the maintenance of that firm’s independence in the conduct of its auditing functions. The Audit Committee’s pre-approval policy provides for the pre-approval of audit, audit-related, tax, and other services specifically described by the committee on an annual basis, and unless a type of service is pre-approved under the policy, it will require separate pre-approval by the committee if it is to be provided by the independent auditor. The policy authorizes the committee to delegate to one or more of its members pre-approval authority with respect to permitted services.
